docker/CHANGELOG.md

Changelog

0.8.1 (2014-02-18)

Builder

• Avoid extra mount/unmount during build. This removes an unneeded mount/unmount operation which was causing problems with devicemapper
• Fix regression with ADD of tar files. This stops Docker from decompressing tarballs added via ADD from the local file system
• Add error to docker build --rm. This adds a missing error check to ensure failures to remove containers are detected and reported

Documentation

• Update issue filing instructions
• Warn against the use of symlinks for Docker's storage folder
• Replace the Firefox example with an IceWeasel example
• Rewrite the PostgresSQL example using a Dockerfile and add more details to it
• Improve the OS X documentation

Remote API

• Fix broken images API for version less than 1.7
• Use the right encoding for all API endpoints which return JSON
• Move remote api client to api/
• Queue calls to the API using generic socket wait

Runtime

• Fix the use of custom settings for bridges and custom bridges
• Refactor the devicemapper code to avoid many mount/unmount race conditions and failures
• Remove two panics which could make Docker crash in some situations
• Don't ping registry from the CLI client
• Enable skip_block_zeroing for devicemapper. This stops devicemapper from always zeroing entire blocks
• Fix --run in docker commit. This makes docker commit store --run in the image configuration
• Remove directory when removing devicemapper device. This cleans up leftover mount directories
• Drop NET_ADMIN capability for non-privileged containers. Unprivileged containers can't change their network configuration
• Ensure docker cp stream is closed properly
• Avoid extra mount/unmount during container registration. This removes an unneeded mount/unmount operation which was causing problems with devicemapper

• Clean up archive closing. This fixes and improves archive handling
• Fix engine tests on systems where temp directories are symlinked
• Add test methods for save and load
• Avoid temporarily unmounting the container when restarting it. This fixes a race for devicemapper during restart
• Support submodules when building from a GitHub repository
• Quote volume path to allow spaces
• Fix remote tar ADD behavior. This fixes a regression which was causing Docker to extract tarballs

0.8.0 (2014-02-04)

Notable features since 0.7.0

• Images and containers can be removed much faster

• Building an image from source with docker build is now much faster

• The Docker daemon starts and stops much faster

• The memory footprint of many common operations has been reduced, by streaming files instead of buffering them in memory, fixing memory leaks, and fixing various suboptimal memory allocations

• Several race conditions were fixed, making Docker more stable under very high concurrency load. This makes Docker more stable and less likely to crash and reduces the memory footprint of many common operations

• All packaging operations are now built on the Go language’s standard tar implementation, which is bundled with Docker itself. This makes packaging more portable across host distributions, and solves several issues caused by quirks and incompatibilities between different distributions of tar

• Docker can now create, remove and modify larger numbers of containers and images graciously thanks to more aggressive releasing of system resources. For example the storage driver API now allows Docker to do reference counting on mounts created by the drivers With the ongoing changes to the networking and execution subsystems of docker testing these areas have been a focus of the refactoring. By moving these subsystems into separate packages we can test, analyze, and monitor coverage and quality of these packages

• Many components have been separated into smaller sub-packages, each with a dedicated test suite. As a result the code is better-tested, more readable and easier to change

• The ADD instruction now supports caching, which avoids unnecessarily re-uploading the same source content again and again when it hasn’t changed

• The new ONBUILD instruction adds to your image a “trigger” instruction to be executed at a later time, when the image is used as the base for another build

• Docker now ships with an experimental storage driver which uses the BTRFS filesystem for copy-on-write

• Docker is officially supported on Mac OSX

• The Docker daemon supports systemd socket activation
